The Crossover Fuzz is a swirling filter-fuzz engine built for radical tone design. It splits your signal into high and low bands and then lets you obliterate or refine each side with independent GAIN and VOL. A single FREQ control sweeps linked low-pass and high-pass filters across the spectrum, while RES pushes from tasteful resonance to nasty oscillation for head-turning textures. Thanks to the pedal’s HIGH/LOW inputs and outputs, you can run it mono, bi-amp, stereo split, or summed, opening up creative routing—send lows to one amp and highs to another, or sling frequencies around the room. For motion on demand, the FREQ EXP jack takes an expression pedal or 0–5 V CV (TRS mapped Tip=Out/Ring=5 V/Sleeve=GND), and the reactive LED display shows where your crossover sits; choose your stage vibe with internal Sky Light (LP=Yellow/HP=Cyan) or Cyber Light (LP=Red/HP=Blue). All-analog path, 9 V DC center-negative, 120 mA, and a rugged enclosure sized at 5.73" × 5.2" × 2.37" (18.5 oz).z
